Originally posted by Chex If they made a FF mirrorless system, I think those wanting it in a DSLR format would at the very least wait and see how well the EVF is, if it has an optional OVF, the processors speed and shutter lag etc.. the biggest advantage for Pentax going mirrorless HAS to be an improvement of the AF system. And with that there's little reason they can't have a faster flash sync speed and other things that should be able to be done via firmware.
An optional OVF?? How would that work? A slot on the side in which you can shove the optional mirror?? An optional EVF hotshoe attachment can work, OVF can't.
Anybody who's THAT serious about photography that they require a FF, also requires an OVF. An FF camera with EVF would be like a F1 racecar with 80 dollar Toyo tires on it.
The ONLY advantage of an EVF system is the big bright viewfinder with the disadvantage of low resolution and lag. The OVF on a FF camera has a big bright viewfinder with the added advantage of unlimited resolution and unlimited speed.
